“There’s one scene, for example, where they’re giving each other Indian burns – that kind of sibling thing.

“CBS wanted me to do the whole season, but I have my [talk] show,” Lake says. “I’ll do at least six [‘King of Queens’] episodes this season, and we’ll see if I have time to do more, maybe next season.”

Lake says she’s just signed on for another four years of “Ricki Lake,” now entering its eighth season in the dwindling field of talk shows.

“I won’t be doing [the show] beyond that, if it lasts that long,” she says. “They’ll either pick me up, or they won’t.

“But I love doing my show,” she says. “It’s constantly evolving, and it’s very different from some of the other titillating shows out there.

“And we’re still number one among women 18 to 34 years old.”

Lake – who made her name as an actress in John Waters’ movie, “Hairspray” and has a cameo in his latest, “Cecil B. Demented” – says she’s been re-infected with the acting bug.

“I wound up doing ‘The Vagina Monologues’ this summer, and it got my [acting] juices flowing,” she says. “For the longest time, I didn’t want to act, but doing that play I thought, ‘Wow, I can be funny!’

“And I love acting before a live audience,” she says. “And ‘King of Queens’ is taped in front of a live audience.”

Lake says she was offered a series pilot this season but passed on the deal.

“As much as I wanted to do it, I couldn’t walk away from my sure thing, the talk show,” she says. “Financially, it didn’t make sense.

“But if [‘King of Queens’] works out, a lot of good things can happen,” she says. “They’re hoping I’ll bring in the younger demographic that watches my show.”

Lake is busy training for a 60-mile walk in October that will benefit breast cancer research and will take her from Bear Mountain to Manhattan along with thousands of others.
